I bought this Sensor IV batwing antenna when redoing my Sunline and later bought the wall plate amplifier not knowing that there's already an amplifier in the head of the antenna. It just hasn't been working right so after a little research and looking at what I have I've learned it isn't the right combo. Can anyone advise which wall plate would go with this antenna?

Here's a shot of the inside of the antenna head, followed by front and back of the wall amplifier I have.

I would replace your current wall plate with a Winegard Sensar Pro. It will work great with your Sensar IV head. It allows you to fine tune the direction of your antenna by watching the strength readings. Also, if you do get the Sensar Pro, it defaults to a gain of 10. It doesn't state such in the manual, but the gain level can be set all the way to 20 for max gain.

Hey thanks for the suggestion man! That's a great idea I haven't thought about and will make tuning so much easier. Will be ordering tomorrow.

I couldn't tell from your pictures how the screws on your original wall plate mounted in the opening. My Sensar Pro had a template cutout that had two little nubs left in the paneling that I figured would crack as soon as I screwed into them. I used the included backing plate that came with my Sensar Pro and mounted it using some machine screws and lock nuts. The lock nuts were inserted thru the cutout opening. Then I mounted the Pro to the affixed backing plate. Also, You can now get the Sensar Pro in either black or white to best match your decor.

A few things.. The wall plate you have is NOT an amplifier, it is the power supply for the one on the roof,, If you disconnect the cable from the roof antenna and hook up either a test lamp or volt meter you should see normal battery voltage at the end of the cable when the unit is turned on.

Second.. There are Sensar 1, II III and IV from what I understand.

1 is unamplified and no longer made

II is amplified, basic batwing

III has the wingman added

IV is an III with a 2nd amplifier (The Winegard Sensar Pro) indoors.

At least that is how I understand it. I may be wrong as I do not work for winegard. Just use the dang thing.

Home is where I park it.
